Discrete stratified Morse theory for 2-dimensional simplicial complexes

The main objective of this thesis is to analyze a generalization of Morse's theory in the case of stratified spaces. The content is divided into three main parts. In the first part we present the background of the classical Morse theory, the discrete Morse theory of Forman and the stratificatio...

Descripción
Sumario:The main objective of this thesis is to analyze a generalization of Morse's theory in the case of stratified spaces. The content is divided into three main parts. In the first part we present the background of the classical Morse theory, the discrete Morse theory of Forman and the stratification of a certain type of topological spaces. In the second part we describe the basic concepts in classical complexity and parameterized complexity. In the last part we analyze two main topics: Lewiner's algorithm for 2-simplicial complexes and the analysis of the complexity of the problem of finding Morse functions in the case of parameterized complexity.
